Add category field to all 75 catalog entries and implement
category-based grouping in both audit output and upgrade prompts.

Categories: python, node, go, rust, ruby, php, shell, git,
devops, platform, ai, general

Changes:
- catalog/*.json: Add category field to all tools
- cli_audit/render.py: Group audit table by category with headers
- scripts/guide.sh: Category-level prompts with skip/all options
  - [Y/n/a=all/s=skip-all] at category level
  - CATEGORY=python,go filter support
  - --categories to list available categories
